How to Replace Rear Brake Pads : Removing the Caliper Mounting Brackets
1 00:00:01,760 --> 00:00:04,310 MARK BLOCKER: In this segment, we're going to cover part two of removing the brake pads 2 00:00:04,310 --> 00:00:10,700 and caliper mounting bracket. We've already got the brake pads off, so part two will be 3 00:00:10,700 --> 00:00:15,290 removing caliper mounting brackets. Once the pads are out, to remove the rear caliper bracket, 4 00:00:15,290 --> 00:00:21,240 we use these 214mm bolts that are located on the backside. I know that it will be hard 5 00:00:21,240 --> 00:00:26,50 to see from that camera angle, but they're pretty much directly behind where the top 6 00:00:26,50 --> 00:00:35,219 portion of the caliper bracket hangs over the rotor there. And these are considerably 7 00:00:35,219 --> 00:00:40,449 tighter than the calipers themselves. Require a little bit of extra torque to get them to 8 00:00:40,449 --> 00:00:50,379 break free. But once you get them, as you see, I kinda brace myself and give it a good 9 00:00:50,379 --> 00:00:59,690 solid, hard yank on the ratchet. And that initial good yank is kinda what's required 10 00:00:59,690 --> 00:01:03,469 sometimes to break the bolt initially free. And when I did so, I positioned my body back 11 00:01:03,469 --> 00:01:07,370 from the car because when I yank that hard amount of force, if you happen to move the 12 00:01:07,370 --> 00:01:12,500 car or want a tendency to slide it off jack stand, my body is set aside from the vehicle. 13 00:01:12,500 --> 00:01:17,430 So if it should go down, I'll have adequate clearance to not be in the path of injury. 14 00:01:17,430 --> 00:01:22,441 Once I break it down free, I just want to come down and get the other one before we 15 00:01:22,441 --> 00:01:34,460 try and get them both off. Now, the next bolt down has a little bit of a clearance issue 16 00:01:34,460 --> 00:01:39,160 with the rear trailing arm. Now, the trailing arm is what centers that actually hold it 17 00:01:39,160 --> 00:01:45,710 in and gives it the ability to have the suspension movement up and down. And behind where the 18 00:01:45,710 --> 00:01:48,250 bolt is located, there's a limited amount of clearance between the nut or the bolt itself 19 00:01:48,250 --> 00:01:52,659 and the trailing arm. It makes a little bit difficult to get the socket and ratchet in 20 00:01:52,659 --> 00:01:56,800 there. Sometimes, you have to come at it a couple of different angles until it slide 21 00:01:56,800 --> 00:02:02,870 on easily. And once you're on it, you just gotta go ahead and break it free again. Now, 22 00:02:02,870 --> 00:02:06,20 this awkward situation, although in this side of the car I don't have much movement, room 23 00:02:06,20 --> 00:02:13,719 to apply any torque, and I can't get my body weight behind it, this would be one of the 24 00:02:13,719 --> 00:02:18,549 times where you get to switch position and use a pushing force on it. And as you could 25 00:02:18,549 --> 00:02:24,870 see from this position, I've got more available space in it in order to get some torque applied 26 00:02:24,870 --> 00:02:28,90 to the ratchet. I mean it's easier for me to break that bolt free. In this particular 27 00:02:28,90 --> 00:02:34,859 situation, my hand or the ratchet will come off of the bolt should go forward. I could 28 00:02:34,859 --> 00:02:39,670 easily smack my fist into that inner thin wall, damaging my knuckle. So, while pushing 29 00:02:39,670 --> 00:02:42,379 forward, I'm going to keep an open hand. In that way if anything slips, I've got an open 30 00:02:42,379 --> 00:02:47,340 hand to just push out and grab contact. And I could spread the force of that impact across 31 00:02:47,340 --> 00:02:53,900 the whole open hand rather than just placing it on a very small area of my knuckles which 32 00:02:53,900 --> 00:03:01,480 damage easily. Okay, now I've got that broken free, I'll just go ahead and remove both the 33 00:03:01,480 --> 00:03:07,610 bolts with my fingers. And I'm going to switch back to the other position because it has 34 00:03:07,610 --> 00:03:15,120 better accessibility for camera angles. And, again, as before with the other bolts, it's 35 00:03:15,120 --> 00:03:21,560 easier to--once you've got them broken free, if they move freely with your fingers, you 36 00:03:21,560 --> 00:03:23,459 get a little bit more clearance in there so it's easier to do it and faster with your 37 00:03:23,459 --> 00:03:30,590 fingers than it is with a ratchet. And they have lock washers on the bolt as well, and 38 00:03:30,590 --> 00:03:32,451 I just want to make sure that each one of them got it and you keep it with the bolt. 39 00:03:32,451 --> 00:03:38,779 And I'll just continue removing this second bolt with my fingers. And this is one of those 40 00:03:38,779 --> 00:03:42,270 applications where one of the newer styles of ratchet wrenches, where one end of the 41 00:03:42,270 --> 00:03:47,249 box wrench is enclosed and it's got a ratchet device in it where the wrench will slide over 42 00:03:47,249 --> 00:03:52,970 the nut or socket or a bolt that you're using. It allows you that ratchet movement back and 43 00:03:52,970 --> 00:03:56,379 forth, whereas the old style box wrench, you would have to put it on, you get so much turn, 44 00:03:56,379 --> 00:04:01,829 you have take it off, and re-grip and get another bite to make a certain amount of movement 45 00:04:01,829 --> 00:04:07,639 again. The ratchet wrench went in there usually in the space area that we had to work with, 46 00:04:07,639 --> 00:04:11,939 and it could have made the job easier. And that's the difference. We can get the job 47 00:04:11,939 --> 00:04:16,139 done with this minimal amount of tools, but there are always specialty tools of that design 48 00:04:16,139 --> 00:04:21,970 that can make the job easier and faster for you. And if you do a lot of your own home 49 00:04:21,970 --> 00:04:25,130 maintenance and auto repair and stuff of that nature, some of those specialty tools can 50 00:04:25,130 --> 00:04:33,400 really be a good asset to your tool set. For most practical, extensive or for the bare 51 00:04:33,400 --> 00:04:39,120 minimum to get you by, a basic tool set will do the job. As you go along and see, there 52 00:04:39,120 --> 00:04:43,630 are a lot of tools that can make it easier and faster but they're really not required 53 00:04:43,630 --> 00:04:48,1 to get the job done. Okay, after removing the second bolt, once again, make sure the 54 00:04:48,1 --> 00:04:52,0 lock washer is there, keeping the bolts together. We'll set them apart from all the other parts 55 00:04:52,0 --> 00:04:56,621 in here in just a minute. After both of those are removed, the caliper mounting bracket 56 00:04:56,621 --> 00:05:04,571 comes right off. It just slides out. That will conclude the caliper mounting bracket 57 00:05:04,571 --> 00:05:08,840 part two. Please watch our next segment on rotors.
